TONGUELESS CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 441,179, dated November25, 1890.

Application filed September 24, 1890. Serial No. 366,028. (No model.)

To all whom it may concern:

Be it known thatI, JOHN M. LONG, of Hamilton, Butler county, Ohio, haveinvented certain new and useful Improvements in Tongueless Cultivators,of which the following is a specification.

Attention is directed to the patent of John M.W. Long, (not theundersigned,) No. 320,919, of November 10, 1885, for cultivators. Thatpatent goes somewhat fully into the general construction of tonguelesscultivators.

My present invention relates to improve ments in tongueless cultivatorsof the general class set forth in said earlier Long patent, and thepresent improvements will be readily understood from the followingdescription, taken in connection with the accompanying drawings, inwhich Figure 1 is a side elevation of a tongueless cultivator embodyingmy present improvements; Fig. 2, a perspective view of one of thestandards with its immediate attachments; Fig. 3, a plan of the matterof Fig. 2, the standard, however, appearing in horizontal section in theplane of line b; and Fig. 4, a vertical section of the axle and foot ofthe standard in the plane of line b.

In the drawings, A indicates the arch-bar; B, one of the standardspivoted at its top to the arch-bar and carrying at its base the stubaxlefor one of the implement-wheels; O, the stub-axle mounted in the base ofthe standard D, the appropriate one of the implementwheels mounted onthis stub-axle; E, the coupling-block mounted on the stub-axle, and Fthe appropriate one of the cultivator-beams coupled at its forward endto the couplingblock.

All the parts thus far referred to are substantially the same as in theearlier Long patent. The arch and beams are supported by theimplement-wheels The beams may be swung to the right or left, swingingon the vertical pivots which unite them to their coupling-blocks. Thebeams may be raised and lowered, oscillating on the stub-axles ashorizontal pivots, and the base of I either standard may swing back orforth relative to the base of the opposite standard, the archbar formingthe pivot of oscillation as such movement takes place, this fore-and-aftindependent movement being the result of one of the horses of the. teampulling somewhat ahead of the other horse.

Proceeding with reference to the drawings, G indicates a clevis pivotedto the stub-axle, so as to be capable of oscillation with reference tothe beam and standard, the clevis projecting to the front of theimplement and having its forward extremity arranged as a the team; H, aprolongation of the clevis to the rear of the stub-axle, thisprolongation terminating in a dragshoe; J, a bail pivoted to theplow-beam near the coupling; K, a spring connected with this bail andextending forwardly and having'its forward end attached to the clevisforward of the stub-axle; L, a stop-rib upon the clevis at the base ofthe standard; M, a stop-lug upon the base of the standard, adapted tocome into contact with the stop-rib when the forwardend of the clevisassumes a certain position of elevation with reference to the angularposition of the standard upon the stulo-axle, and N a similar stop-lugupon the standard, adapted to make contact with the stop-rib when theforward end of the clevis is in a certain position of depression withreference to the standard.

WVhen the parts are in the position indicated in Fig. 1, it isassumed'that there is no forward draft upon the clevis. circumstances itwill be obvious that the spring K, straining between the plow-beam andthe forward portion of the clevis, serves to hold the forward end of theclevis in a maximum elevated position, this maximum being limited bycontact of the clevis-shoe with the ground. With the clevis thuselasticallybut firmly held in such position, it will be understood,especially by reference to Fig. 4:, that the top of the standard canswing no farther forward than the stop-lug M willpermit and that it canswing no farther backward than the stop-lug N will permit. The top ofthe arch is thus at liberty to swing back and forth alimited distanceonly. The clevises thus support the arch, While permit ting it to have alimited motion. It will be obvious that the base of one of the standardsmay swing to the rear and the base of the other standards swing tothefront as far as the limitations of the stops will permit, thus providingfor the independent fore-anddraft hitch-point for the appropriate horseof Under such IOC aft movement of the two cultivators. Thehitch-point'at the forward end of the clevis, when the clevis is in theposition indicated in Fig. 1, is to be above the line of draft, the lineof draft being a line cutting the tracehitch at the horses collar andthe center of the stub-axle. The result of this is that when thedraft-strain comes upon the forward end of the clevis the forward end ofthe clevis will be depressed, and the shoe willbe carried entirely clearof the ground, the spring K yielding to permit the clevis to take itsnew position. Such new position would be the normal workingposition ofthe clevis, which under the new condition still continues to support thearch and permit of its proper fiexation, as called for by variations inthe relative fore and aft positions of the two stub-axles. It will beobserved that the bail J is a mere expedient for connecting the springwith the cultivator-beam.

I claim as my invention The combination, substantially as set forth, inan arch-bar tongueless cultivator, of a clevis pivoted to thewheel-axleand provided at its forward end with a hitch-point and projecting to therear of the axle, a spring engaging the clevis and the cultivator-beamand arranged to elevate the forward end of the clevis and press its rearend to the ground, and stops to limit the oscillations of the cleviswith reference to the arch-standard.
